3 out of 5 eggs5GHZ hollow promise

Pros: 2.4 GHZ is incredible. Easy install and driver install.

Cons: 5GHZ it a total waste. 5 bars 300MBS on 2.4GHZ. 2 bars 54MBS on 5GHZ. 8 feet between router and adapter antennas. Corner of a wall is between them and that apparently is enough to severely hinder 5GHZ band. May just be 5GHZ and have nothing to do with this card.

Other Thoughts: Like the card. Like TP-LINK products. Using their cards in other PCs in my house and I have the TP-LINK wireless N dual band router. Just wish I had saved my self $10 and bought the TP-LINK wireless N 2.4GHZ card and stayed away from dual band 5GHZ card and router. Lots of promise but no actual delivery of speeds promised.

1 out of 5 eggsBare Minimum

Pros: It was functional.

Cons: This device doesn't get even half of the speeds that it promises with minimal range from the router, and near 100% signal strength. It took three weeks to return the item, just to have it turned down due to a faulty serial number that was sent to me.

Other Thoughts: Don't buy it unless you want trouble.

5 out of 5 eggsGreat wireless for the price

Pros: If you are looking for a PCI-Express wireless adapter for your PC that "just works" and isn't too expensive, this is a good place to start.

The technical details have been covered in other reviews, but I wanted to rave about the single most impressive feature of this card: Reliability.

I live in a 2-floor, 2100 square foot house. I've reviewed many wireless-N devices before, so I was expecting about the same performance as those.
I was wrong.
The most unexpected thing about the TP-Link was the 54% signal strength from the other side of the house, on a different floor, through a ventilation duct, metal bed frame, and 5 walls.

To put it in perspective, even the expensive 802.11AC devices such as the DWA-182, which cost several times as much (though are different classes of device), had unreliable connections at best. I could view images and check email, but not stream movies without losing connection every few minutes.

To contrast, the TP-Link N600 never lost connection when copying over 230GB of files.

Other notes I made:

+ Supports 5GHz networking. Why should you care? The more common (and also supported) 2.4GHz frequency can be very flaky and unpredictable. Microwaves, bluetooth devices, and even garage door openers can interfere with your network.
5GHz networks generally do not have this problem.

Which should you choose?
It depends on your situation. this card supports both, so try both! See what works best for you!

+ Supports low-profile cases with the included adapter.

+ Warranty is 2 years -- twice as long as most other adapters. Really, twice as long as most other computer products of any kind.

Cons: - The drivers come in a mini-CD. This is fine for most computers, but many CD-ROM drives, especially older ones, do not work well with them.

- Ships with old drivers. Any geek, however, should know to always get the latest drivers from the website.

- Signal was much weaker when passing through my aluminum computer case, Easy enough to fix: Move the computer.

- As a PCI-Express card, obviously this product is not mobile. Moving my computer across the house to test was a little awkward.

Other Thoughts: I installed high-gain antennas and saw almost zero difference at any range. The included antennas appear to be very good.

4 out of 5 eggsWorks great

Pros: Works great. Works in linux. Decent speeds to my wireless N router. I don't use this for gaming but I do use it for every-day use. Works well for that.

Cons: None

5 out of 5 eggsgreat mid level NIC

Pros: Dual band nic (network interface card) at 2.4 ghz and 5 ghz which affords those w/ dual band routers to choose which connection to utilize.

Great 2.4ghz performance, decent 5ghz performance. Which I would say is more a limit of the 5ghz band's lack of ability to go through surfaces and the current location of my workbench PC's.

I have an average sized home at 1550sq ft and my workbench sits 1 floor down on the far side, ~60 ft away) from my router. From this location i'm able to get an 85% LINK and 85% signal strength connection at 300mbps on the 2.4ghz band.

On the 5ghz band i'm getting peaks at 300mbps, but the connection speeds are inconsistent. I am getting about 2-3 bars of connectivity and ranging from 81mbps to 300mbps.

I tested this nic against a couple USB nic's and another tp-link pci1 nic. I used the Rosewill N900UBE, Netgear WNA1000m, and the TP-LINK TL-WN881ND.

Comparatively, the Rosewill product was 100 link, 100 strength, and 300 mbps. However, this product works via USB with a +5 db boost antenna.

The Netgear product is a nano USB NIC that is about the size of a USB connector. This product received 120-150 mbps at 100 link and 100 signal. The product is an N150 instead of this TPLink N300 device.

The similar wn881nd performed about the same as this one on the 2.4ghz band. The primary difference between the two is that wn881nd is only 2.4ghz vs this one being either 2.4ghz or 5ghz.

The wn881nd got 85% link and 90% signal strength at 300mbps connection speed. Slightly better than this product, which could have been due to additional device interference rather than a fault of this device.

Overall, this device performed great. There were no connection drop outs, always providing a great networking connection.

Cons: If I had to write about a con, i'd have to say that the PCI1 connection is the biggest con. For power users, there is no issue with adding a pci card, however, for many users this may be a daunting task.

The biggest issue is due to some OEM manufacturers utilizing a sticker to prevent users from opening their case to service &/or upgrade their big box computers w/out voiding their warranty.

Overall, this is not a major con, but worth noting.

Other Thoughts: The included bracket for small form factor PC's is a great addition that makes the product that more versatile.

5 out of 5 eggsIt works...

Pros: So far the signal has been consistent; minimum to no buffering when streaming; but then again it also comes down to your router. So far my speed has been at 144, yet again it comes down to router.

Haven't run into any problems, it is also mac compatible and runs right out of the box. If your doing a mac clone build.

Cons: none

1 out of 5 eggsPiece of trash

Pros: None

Cons: The driver is a nightmare running on windows 8.1. There are three drivers listed when trying to update and none of them work (including the ones listed directly on TP-links website). The adapter works fine for a few minutes, then it cuts out and needs to be reset. I cannot even download a 240 mb podcast on fios, because it cuts out that quickly. When it is working, my samsung galaxy and surface 2 outperforms my desktop. Look elsewhere if you want to access the internet.

3 out of 5 eggsPoor range

Pros: Easy enough to install

Cons: Does not keep a consistent connection with a router approximately 25ft away in the same apartment. It isn't a clear shot but I am still not pleased with that performance.

Manufacturer Response:

Hello Customer,

Thank you for checking out our Adapter.

One suggestion if you haven't already done so is to update the Driver of this device.

This driver can be found on our website at:

Also keep in mind that the 5GHz band will not travel as far as the 2.4GHz.

If you are using the 5GHz and there is obstruction like walls or doors, then you may find that this distance is too far.

Please feel free to contact me directly at for any issues or concerns.

Best Regards!

5 out of 5 eggsWorks without a problem.

Pros: 2.4Ghz and 5Ghz
Good security features
Compact size
Effective Antennas
Runs at fast speeds.

Cons: I cannot find any.

Other Thoughts: I have been running my desktop with a powerline for over a year now. The powerline technology gives full speed of a direct connection anywhere in your house, which gives great performance. This card has worked well enough I have decided to use it always instead of my powerline.

The first really good thing I found about this device is that it works on the 5Ghz frequency. There are many electronic devices in the world today like wireless headphone technology that works on a 2.4Ghz frequency. The problem with that is that it can interfere with wireless internet which operates on the same frequency. Combining this wireless card with any 5Ghz wireless router should allow you to avoid interference with any other electronic devices. This has proven very helpful.

After this, there are other aspects of this device that work extremely well. Despite the antennas being only about 2.5 inches long, they work perfectly. I have a lot of difficulty even with my laptop picking up wireless in this room of my house. I used a Rosewell wireless card with much larger antennas and that allowed my desktop to connect but often only had 1 bar of signal strength. This device most of the time works with 3 bars of signal strength, in the same position, with antennas less than half the size.

For the other features of this device, they are pretty ordinary. There is no trouble connecting to a secured network, and speeds seem to be overall good. I was not able to test the transfer speed to its max potential, but it works exactly the same as the wired connection did. It works well enough you cannot notice which means its excellent fast service always. While loading videos I only ever noticed pauses when my brother was playing videos and playing online games at the same time, and it comes as a result of my limited internet package to my Internet Service Provider. Whenever he was not doing this, the device works perfectly without even a pause on high definition video streams.

I highly recommend this device to users because the fact that it does work so easy without any problem. That is the mark of a good network device. That you put it in, and it works without ever needing any maintenance or other interactions. If it occasional quits working then its a bad device, but this one has had no problems since receiving it. It works flawlessly.

I would highly recommend it for anyone. It has everything you need for a fast modern network.

4 out of 5 eggsEasy install and it works

Pros: Easy to install, just insert the card into a PCI-e slot, attach the two industry standard antennas, and Windows 8 does the rest.

I did not install anything from the included mini CD. Windows 8 installed the Driver automatically. I used the Wireless manager built into Windows 8 to manage the Card (e.g. connect to my Router via either the 2.4 or 5.0 GHz wireless network). Just move your mouse to the lower right-hand corner of your screen.

Windows 8 indicated I connected at 300 Mbps on both the 2.4 and 5.0 GHz networks. Signal strength was three of five Bars at ~50 feet through one wall.

Also see my 2/10/2013 review of this product. The card appears to be identical to the one I reviewed earlier.

The Box has been updated to show a Windows 8 Logo and Low Profile Bracket (which is now included unlike the earlier card).

Cons: Download speed is rather poor. This may not be the fault of the card (since it is lower than my earlier test, I am still investigating). My laptop runs ~12 MB/sec for both both upload and download on 2.4 GHz (laptop does not support 5.0 GHz).

I measured the following between the TL-WDN3800 adapter and a TL-WDR3600 router (to/from a Gigabit Wired PC):
- 2.4 GHz: Upload 9.1 MB/sec, Download 2.8 MB/sec
- 5.0 GHz: Upload 13.2 MB/sec, Download 4.1 MB/sec

I saw similar speeds when initiating the Tests from the Wired PC. That is, much lower transfer rate when a file is transferred towards the Wireless PC (vs. away from).

Other Thoughts: Having the option of both 2.4 GHz and 5.0 GHz is desirable in areas with high external air-space interference.

Wireless Standards will likely shift from 802.11 a/b/g/n (a, b and g are already obsolete) to the new 802.11 ac, but this will take some time. Likely your Modem is the bottleneck on your Internet network anyway.

The TL-WDN3800 adapter is the third in a series of four TP-LINK wireless adapters (PCI Express x1) TL-WN781ND (150 Mbps @ 2.4 GHz), TL-WN881ND (300 Mbps @ 2.4 GHz), TL-WDN3800 (300 Mbps @ 2.4 or 5.0 GHz), TL-WDN4800 (450 Mbps @ 2.4 or 5.0 GHz).
